Jan Bonney wants his Rosslyn Park players to prove they have what it takes as they end their season at Blackheath on Saturday.

Park were National One leaders at the beginning of the year but have suffered a terrible run of form since then, losing six of their past 10 games and slipping to fifth in the table – where they are guaranteed to finish no matter what Saturday’s at their derby rivals.

Bonney has threatened to make a raft of changes in the summer and has told his squad they have one last chance to show they can be part of a team capable of challenging for promotion next season.

“You are remembered by your final game,” he said.

“If people finish the season off with a bad performance that is how they are going to go into pre-season.

“People need to consistently perform and there’s some guys that have not been.

“There will definitely be a few changes this summer as this will be my first year of being able to recruit players as I came in with this group last year.

“We have got a few guys that are retiring and the majority of the squad want to stay, which is good.

“Then it is just a case of us adding in players to enhance us and make us better.

“You need 120 points to win this league and we are going to end up on 90 with a bit of luck.

“So my job now is to recruit guys that will enhance the squad and make it more competitive for next year and get us nearer that 120 point mark.”

Park’s miserable form continued with a 21-8 loss at Blaydon on Saturday and Bonney wants an end to the errors that have cost his side a shot at promotion this year.

“We probably had 75 per cent of possession against Blaydon but made a lot of errors again,” he added.

“That seems to be the thing that keeps coming up – individual players making silly mistakes at the wrong time.

“It is frustrating more than anything else as we are more than capable of being in a higher position.

“I am not saying we are good enough to go up but we are better than where we are in the league and that is disappointing.

“We can go to Blackheath and win but it is a matter of how many errors we will make and how many penalties we will give away.”
